Yes, every card can be sold for EOS. Normal ones go for 0.01 EOS, rare ones go for 0.1 EOS, epic 1 EOS, legendary 10 EOS. Silver and gold cards can go even higher, depending on the rarity. The problem is there is not enough liquidity, a lot of cards are not interesting to buy. I did buy some but I haven't sold any yet.
